8Packs no BS testing Intel 8700K and Z370 with Delid 5ghz and above available from OCUK.

Not watched this yet but I'm sure people will be interested.
Although his choice to use a vega GPU and not a 1080ti is questionable.

Yeah, seems it just worsens the GPU bottle-neck situation which hides the 'truth' of how fast each CPU really is. Digital Foundry has the right idea, using an overclocked Titan XP

Exactly, he went to the trouble of using 720p to remove a GPU bottleneck but as you can see its still there!

Tried the ROG 1.80.0 from Asus and also 1.81.0 from the CPU-ID site. Which version are you running? Also same issue with HwMonitor.

1.81.0 what board are you using?

 

[gavinh87]

Ah it might be a bug only present on the wifi model then..

How do people run 5 GHz AVX Prime95? HWInfo shows me almost 300 W power consumption when I try that... Failure is inevitable.

I couldn't without a delid. Now I'm avx stable at 1.344v at 5ghz with temps of around 80c max

Which Prime version and test exactly? What is the power consumption according to HWInfo for you? What about SA, IO and memory? Edit: Looks like I can do 4.9, probably limited by temperature at 5.0.

Yes, its shown perfectly since day 1. Are you on latest CPUz?

Also, 5050 appears to have broken nvidia audio lol. Tried reinstalling GPU drivers etc etc but no luck. Posted on ROG forums hoping for a reply.

Did you guys set current cap 140% in Digi power??

Yeah, new bios is also the same. I'm stumped.

Cache / core current max????

Max this out???

Its above where you set cache ratio.

I've just tried this 255.50 I think is the maximum.
I also set the CPU voltage to 1.4v instead of the usual 1.32v but it has no effect. With AVX offset active, it fluctuates between the frequencies even when not using AVX loads.

Has anyone else experienced this?

Had it on the Z370 Prime-A with factory BIOS, still on the Taichi with factory and 1.16 beta BIOS. Is there a way to confirm AVX instructions are not used? Because every program compiled in the last few yours could potentially use them, correct?

Well im 99% sure battlefield 1 doesn't use avx, nor does forza 7.
If they do however then its just best we overclock to the maximum stable avx frequency.

BF1 certainly doesn't

Might be a global bug with Coffee Lake then.

Yep I'm seeing it too. Not good...

 

[gavinh87]

Well I'm glad it's not just me then!
I'll get hold of Asus later see if I can get them to test this themselves

 

[8 Pack]

No game I ever tested caused the CPU frequency to dip under AVX load even when the platform has AVX offset set. So I am pretty sure games don't have AVX. Try Prime V 26.6 vs AVX version 27.x 28.x see what happens.
